I don't usually do the joke thing, but this one is close to relevant.

Do you know the difference between a northern zoo and a southern zoo?

At a northern zoo, they post the common name of the animal and the
Latin name. At a southern zoo, they post the common name, the Latin
name, and a recipe.

[note: you could substitute "Cantonese" for "southern" in this joke,
too. Any others?] -aem
